Problems solved by technology

Furthermore, because yak skin has dense hair, many hair follicles, many sweat glands, less fibers at the junction of the grain layer and the reticular layer, and weak connection, therefore, due to the large difference in the structure of yak skin and yellow cowhide, traditional processing in related technologies The method of yellow cowhide, which is not suitable for processing (including tanning and soaking, deliming, etc. before tanning) yak leather

Embodiment 1

[0035] The processing method of this yak leather upper leather that the embodiment of the present invention provides, please refer to figure 1 , including the following steps:

[0036] Step 101: Adding yak hide to water, adding soda ash, soaking aid, degreasing agent and preservative to the water, rotating the yak hide and pre-soaking water to obtain the pre-soaked leather material;

[0037] In step 101, after pre-soaking, all dirt, impurities and soluble protein on the yak hide can be removed (by soda ash, soaking aid, degreasing agent and preservative), and the floating meat and oil film on the hide can also be removed. Most of it is removed in the water immersion operation, so that the skin collagen fiber structure of the yak hide is loose and filled with water, which is beneficial to the subsequent operation. At this time, the skin material after pre-soaking in water can be removed and weighed, so that it is convenient to add a predetermined weight in the subsequent operat...

Embodiment 2

[0063] In the present embodiment, the preparation method of the processing method of yak leather shoe upper leather comprises the following steps:

[0064] S1: adding yak hide to water 3-4 times its weight, and adding 0.8-1.2% of soda ash by weight to the water to rotate the yak hide;

[0065] S2: Add the yak hide, 0.3-0.7% soaking aid, 0.2-0.4% degreaser and 0.1% antiseptic into the water after turning for 18-22 minutes, and continue to turn the yak hide for 4 After -5 hours, let it stand until the next day to obtain the leather material after pre-soaking water;

[0066] S3: Add the pre-soaked leather into water 3-4 times its weight, and add 0.8-1.2% of the weight of the pre-soaked leather into the water, and then rotate the pre-soaked leather ;

[0067] S4: After rotating for 18-22 minutes, add 0.8-1.2% water soaking aid, 0.2-0.4% degreaser and 0.1% preservative to the water after the pre-soaked leather, and continue to make the yak skin After turning for 4-5 hours, let i...

Abstract

The invention relates to the field of animal fur processing, in particular to a processing method for yak shoe upper leather. The processing method provided by the invention can process yak leather into upper leather which has a clear and fine grain surface, can reach a contraction temperature above 95 DEG C, is soft and full, achieves good extensibility, excellent teasing property, dyeing property and finishing property and has a few flaws on the yak leather grain surface. Therefore, the processing method provided by the invention can be exclusively used for processing yak leather into upper leather. The yak shoe upper leather produced by the method can improve the utilization rate of yak leather, thereby greatly improving the utilization value of yak leather.

Description

technical field [0001] The invention relates to the field of animal fur processing, in particular to a method for processing yak leather upper leather. Background technique [0002] At present, the leather market is mainly dominated by three major raw materials (pigskin, cowhide, and sheepskin), of which cowhide is mostly yellow cowhide. [0003] In related technologies, the common cowhide processing methods are mostly aimed at yellow cowhide. Compared with yellow cowhide, the collagen fiber bundles in the grain layer of yak leather are fine and tightly woven, while the collagen fiber bundles in the reticular layer are thicker and loosely woven. The two layers are very different and less strong. Furthermore, because yak skin has dense hair, many hair follicles, many sweat glands, less fibers at the junction of the grain layer and the reticular layer, and weak connection, therefore, due to the large difference in the structure of yak skin and yellow cowhide, traditional proc...
